This invention relates-to improvements in pumps, compressors, ventilators and the like of that class in'whic'hthe elements in mol object of the invention being to tion have. continuous-rotary movement the improvements which avoid alternative dislacement and th'e effects of inertia resulting therefrom; to dispense with objectionable lvalves andthe like, and alsoto' reduce to a minimum thesurfaces, engendering friction, r With the above and other objectsv in view, the invention consistsin the construction,

A combination andv arran ementfof devices hereinafter described an .claimed.

In the accompanying/drawings Figure 1 is a vertical, longitudinal, central, sectional view of a rotary ump constructed and arranged in accor ancewith my invention.

Figure 2 is a i transversew'sectional. viw on the plane indicated'bythe line 2-'2 of Figure 1.

Figure 3 is a detail sectional view on the 25 plane indicated by the line of Figure 2.

Figure 4 is atransverse vsectional view 'of a modified form of the invention.

Figure 5 is a similar view of another inodified form ofthe invention.

The pump comprises a ixed casing-- 1 formed by two shellsconnected by a horizontal joint and carrying -a hollow fixed sleeve 2, rforming the suction inlet.

. Coaxially with thecasing 1 is dis osed a drum 3 which is revoluble on the s eeve 2,

a. ball bearing 4 being interposed between drum and sleeve.

This drum is inte al with a shaft 5 itted ,on one side in a bal bearing 6, rovided in -'the casingl, and, on the other si e, in a ballbearing 7 arranged at the extremity ofthe sleeve 2.

The pump comprises two'bodies separated by a partition-8 of the drum 3.

In each of these bodies is disposed a hollow cylinder 9 provided with heads and rotating in ball-bearings 10', the latter' are carl' ried by the sleeve 2 "and mounted'on eccentric bosses 2fL of the sleeves. Each of the cylinders is moved by the drum 3., through the medium of -a vane ll'slidin-g in the walls of the cylinder 9.

Each vane 1s lmaintained at one part in radial recesses 12 provided inthe partition 8 provide` the front of the vane.

-in Figure 2, in orderto allow the vane to assume various positionsy in the cylinder during its rotation, such changes in position being caused by the eccentricity of the cyl-- inder with regard to the drum 3. The vane l 11 is guided in the wall of the cylinder 9' in the front direction, in thedirection of rotation, b a. blade 16 sliding in a recess 17 and pushe by springs 18, and, at the rear, by rollers 19 placed in'recesses provided at the extremities of the cylinder. The blade 16 extends along the whole cylinder 9 and enis formed between the 'cylinders 3 .and 9 in sures the tightness of the chamber -20 which In the sleeve2 are provided apertures or passages 21 disposed to the right of the cylinders '9. These cylinders are provided medially of their circumference with an aperture 22 near .the `vane 'and in rear thereof.

The drum 3 is provided with two ports 23 in the front of the vanes. l

In order to ensure the equilibration, the

two vanesaredisposed at 180 in the drum 3.

In case of .juxtaposition of several elements the `venes would be disposed for the same purpose at equal angles with regard to the different' elements.

Tight joints between the cylinders l9, the bottom parts of the drum 3 and the partition 8 are ensured vby segments 24 pushed vby springs.

Thecasln 1 1s provided with an outlet conduit 2 5' placed for exampleat itsupper art.

It wi1lbe remarked that the vane 11 sep- 7 arates thed chamber 20 from an opposite chamber 2 6 whicl1 .-is. also formed between the cylinder 9 and the drum 3.

While'rotating the shaft 5I in the direction lindicated -by thel arrow sleeve 2 and the passages 21 and 22 into a chamber 26, the capacity of which increases; at the same time the duid contained in the chamber 20, the capacityo whichl is gradually diminished,v will be discharged through 7' in Figure 2, the -transported fluid' will besucked through the.

the passage 23 into the space 27 between the casing 1 and the drum 3 and escapes through sleeve 2 remains fixed, the drum beingmoved in the direction ofthe arrow f.

Figure 4 shows a modified form of the invention, according to which the drum 3 is moved in the contrary direction f', the direction of the circulation of the transported fiuid being simply reversed, the apparatus continuing to operate as a pump.

The fluid is sucked through the passage 23 intothe -chamber 20, the capacity of whichincreases, and at the same time the fluid contained in the chamber 26, 'the capacity of which diminishes, is discharged through the passages 22 and 21 across the Asleeve 2,

through which it escapes.

The same result will be obtained by turn# ing the apparatus in the direction indicated by. the arrow f (Fig..l2), by modifying the position of the orifices 22 and 23 with regard to the vane, that' is to-say, the orifice 22 would have to be placed inthe front of the vanein the.directionv of rotation and the orifice 23 at the rearI ofthe same.

'In some instances it would be possible to dispense with .the casing 1 which is practically without utility if the fluid is air sucked directly from the W\Leri0r.

Inversely, when rotatin the apparatus in the direction of f', the ori ce 22 being laced in front of the'vane in the direction o rotation and the orifice 23 at the rear of the i pallet, it will be obvious that vthe direction of the circulation of the fluid would be from the center toward the periphery.

In the event that the drum 3 is fixed and the sleeve 2 rotated, the inner cylinder 9' would be moved, that is to say Aoscillated circumferentially, analogously to the movement of the eccentric collars, owing `to its fitting on the eccentric bosses 10 of the movable sleeve and the line oftangency of the twocylinders 3, 9 would describe the inner circumference ofthe drum 3, whereas the vane 11 would remain immovable, being preferably disposed in the vertical diametri-v cal plane at the upper or at the lower point. This form of the invention is shown in Figure 5.v

The casing 1 is dispensed with since the outer drum is fixed. v 4 According to the directionv of rotation of the sleeve the fiuid will circulate from -the center towardthe periphery or inversely,

and the orifices 23 will be the orifices of "or a higher number of similar bodies;

discharge 4or intal're. If the direction of rotation is the onerepresented in Figure 5 by the arrow f, it will be obvious that the working of the appartuswill be the same as described with regard to the 'form shown inFigures lite 3, since the relative motion is the same..

If the direction of rotation is the 'contrary one, the discharge willbe effected' across the shaft 2. Suchl an arrangement is preferable in case of employment of apparatus as overfeeder for explosion motors in order to blow the'carburetted gases` and to avoid the disadvantages resulting from the separation of the gaseous mixtures resulting from their vdifferent densities, the mixture being in this case and also in other analogous cases,

sucked from the eirteriortoward the interior.

4In the device represented in Figure 5, the rotation can be also effected in either direction by suitablyv disposing the orifices of intake and discharge on both sides of the Hence, the apparatus is reversible with regard to the direction of rotation as well as with regard to the role of the fixed and th movable elements.

The pump may comprise one single body,

The invention permits, without departing from the scope of the same, different modifications of the details. For example, for pumps of large dimensions, the guiding elements 16, 18 and 19`could be advantageously replaced by another appropriate guiding system', for-example a cylindrical piece rotating or pivote'd in lodgings provided in projections of the inner cylinder and comprising a longitudinal slit into which passes vthe vane with slight friction.
